Understanding Safe Paint Storage Requirements

Paints are considered “flammable and combustible materials” according to OSHA. Storing large volumes of paint can be extremely dangerous; avoiding safe paint storage requirements may result in fines and other penalties. Proper paint storage buildings can help protect personnel and facilities that handle, store, mix and dispense paints and other flammable liquids.

Paints or other flammable liquid storage that exceeds 60 gallons must be stored in a paint storage building to protect flammable liquids against flash fire, prevent paint containers from building excessive internal pressure and contain flammable liquid spills or leaks. Depending on their location in relation to other buildings or property lines, indoor and outdoor storage buildings may require fire-rated construction listed by the National Fire Protection Agency (NFPA 251-1969). OSHA requires all indoor paint storage buildings to contain the following:</P.

Paints contain additives, pigments and chemicals that can be harmful to humans and the environment if not disposed of properly. Paint waste, whether liquid or solid, must be properly disposed of in a flammable storage containment for paint that can handle proper flammables and hazardous materials.

Safe Paint Chemical Storage Buildings

The two major types of paint are oil-based and water-based paints. Oil based paints are manufactured with a petrochemical product, usually mineral spirits or toluene, as a solvent. These paints include enamels, shellacs, lacquers, stains, seals, polyurethanes, and more.

Some paints are more flammable than others and some are more toxic than others. It is necessary that paint classifications are grouped separately to avoid hazardous situations. Grouping paints according to the NFPA 704 hazard classifications sign can provide for a safe and compliant chemical storage environment.

When storing small to large amounts of paint in your facility it is necessary that precautionary measures are met. Keep your paints stored in a fire rated chemical storage building for full compliance.

  1. You stated that “Paints or other flammable liquid storage that exceeds 60 gallons must be stored in a paint storage building to protect flammable liquids against flash fire, prevent paint containers from building excessive internal pressure and contain flammable liquid spills or leaks.”

    But if it is a category 2 flammable or 3, OSHA has it listed as 120 gallons allowed outside a storage cabinet or internal room. Or am I missing something?

    1. Hi Bill, you may want to reference OSHA’s website more closely: It states “Not more than 60 gallons of Category 1, 2 and/or 3 flammable liquids or 120 gallons of Category 4 flammable liquids…” and please note that they mention an inside storage cabinet and an outside storage cabinet. Not outside of a storage cabinet or designed room. The instructions are for storage inside a cabinet that is inside a facility but away from exits, stairways, and passage of people, or an outside cabinet where the placement would depend on the flammability classification.

  2. could you advise if 2k process painting which contains likely isocyanate can cause a explosive atmosphere


    1. We advise you to consult your SDS (Safety Data Sheet” for the paint you use. Methyl Isocyanate and Isobutyl Isocyanate are fire and explosion hazards as well as inhalation hazards. They can react with water or other chemicals. Please follow all state and local guidelines for ventilation and use.
